Description

저장조 내부의 부착광 제거용 빅 블라스터 장치{Big blaster apparatus for removing attached ore in bin}Big blaster apparatus for removing attached ore in bin}

본 발명은 저장조 내부의 부착광 제거용 빅 블라스터 장치에 관한 것으로서, 특히 제철용 광석이 저장되는 저장조 내부에 에어를 솔레노이드 밸브를 통하지 않고 직접적으로 신속하게 공급하므로써 에어의 누풍을 방지하고 저장조 내부의 부착광을 제거할 수 있도록 한 저장조 내부의 부착광 제거용 빅 블라스터 장치에 관한 것이다.The present invention relates to a big blaster device for removing the attachment light inside the reservoir, and in particular, by supplying air directly to the reservoir where iron ore is stored without passing through the solenoid valve, preventing air leakage and attaching the inside of the reservoir. The present invention relates to a big blaster device for removing attachment light inside a reservoir capable of removing light.

일반적으로 제철소에서 사용되는 광석의 경우 종류별로 각각 저장한 후 다수개의 브렌드를 혼합하여 성분을 조절하게 되는데, 상기 광석을 저장하는 빈(bin)을 저장조라 한다. 상기 저장조는 각종의 광석을 필요개소에 효율적으로 배분하기 위해 일시적으로 또는 장기적으로 저장하는 필요설비로서, 광종의 성분, 성품등의 특성으로 인해 그 내부에 부착광이 형성되어 저장조의 효율이 떨어지고, 잔량으로 인한 성분 상이 등의 문제점이 있어 수시로 부착광을 제거해야 한다.In general, in the case of ores used in steel mills, each type is stored for each kind, and then a plurality of blends are mixed to control components. The storage tank is a necessary facility for temporarily or long-term storage in order to efficiently distribute various ore to the required location, due to the characteristics of the components, characteristics, etc. of the light deposits formed therein, the efficiency of the storage tank is reduced, There is a problem such as the difference in the components due to the remaining amount should be removed from time to time.

이러한 문제점을 해결하기 위하여 고압의 에어(air)를 순간적으로 저장조 내부의 국부에 투입하여 이 에어 압력으로 저장조 내부의 부착광을 제거하는 빅 블라스터(BIG BLASTER) 장치가 일반적으로 사용되고 있다.In order to solve this problem, a BIG BLASTER device is generally used in which a high-pressure air is instantaneously injected into a local part of a reservoir to remove adhesion light in the reservoir by this air pressure.

이는 도 1, 도 2에 도시된 바와 같이, 각각의 빅 블라스터(100)에 에어를 공급하기 위하여 콤프레서(101)가 설치되고, 상기 콤프레서로부터 여과된 7~9㎏/㎤ 의 에어가 통합탱크(102)에서 인입된 메인홀더(103)에 의하여 저장조(104) 측면에 다수개 부착설치된 각각의 빅 블라스터(100)에 분배되며, 타이머에 의해 에어탱크로부터 에어가 저장조 내부로 폭발,분사된다.1 and 2, a compressor 101 is installed to supply air to each of the big blasters 100, and 7 to 9 kg / cm3 of air filtered from the compressor is integrated into a tank ( It is distributed to each of the big blaster (100) attached to the plurality of storage tank 104 side by the main holder 103 introduced in 102, the air is exploded and sprayed into the storage tank from the air tank by a timer.

이러한 각각의 빅 블라스터(100)는 콘트롤판넬(105)에서 연동으로 신호를 보내면 중간 솔레노이드 밸브(112)에 의해 작동하고, 또한 각각 설치된 국부 개소의 솔레노이드 밸브(112)에서 수동으로 개별조작을 할 수 있도록 되어 있으며, 상기 메인홀더(103)는 솔레노이드 밸브(112)로 연결되고, 퀵 밸브(107)를 통하여 1차 평형실(108)로 공급되며, 공급된 에어는 피스톤(109)의 중앙홀(110)를 통해 탱크(111)로 공급된 후 압력이 팽창되기 시작된다.Each of these Big Blaster 100 is operated by the intermediate solenoid valve 112 when the interlock signal from the control panel 105 is interlocked, and can be manually operated individually at the local solenoid valve 112 installed. The main holder 103 is connected to the solenoid valve 112, and is supplied to the primary balance chamber 108 through the quick valve 107, the supplied air is the central hole of the piston (109) After being supplied to the tank 111 through 110, the pressure begins to expand.

상기 팽창된 에어는 탱크(111)와 1차 평형실(108)에 같은 압력으로 일정하게 유지되어 있다가 콘트롤판넬(105)의 자동조작이나 개별조작으로 솔레노이드 밸브(112)에서 개도되면 그 부분에서 일부 에어라인(106)에 고압의 에어가 소량 누출되며 1차 평형실(108)의 에어가 누출되는 순간에 퀵 밸브(107)의 순간 동작으로 에어가 누출되는 것을 차단하고, 동시에 1차 평형실(108)과 탱크(111)와의 압력 균형상실로 인하여 피스톤(109)의 후진 동작으로 고압의 에어를 토출구(113)를 통해 분사하여 상기 저장조(104)의 부착광을 제거하는 것이다.The inflated air is kept constant at the same pressure in the tank 111 and the first equilibrium chamber 108, and is then opened at the solenoid valve 112 by automatic or individual operation of the control panel 105. A small amount of high pressure air is leaked to some of the air lines 106, and the momentary action of the quick valve 107 prevents the air from leaking at the moment when the air in the first balance chamber 108 leaks, and at the same time, the first balance chamber Due to the loss of pressure balance between the 108 and the tank 111, the high pressure air is injected through the discharge port 113 by the backward operation of the piston 109 to remove the attachment light of the reservoir 104.

그러나, 이러한 종래의 빅 블라스터 장치는 계속되는 동작중 상기 솔레노이드 밸브(112)에서부터 복잡하게 구성된 에어라인(106)등을 통해 에어가 누출되어 상기 1차 평형실(108)과 탱크(111)와의 압력 평형 불일치로 상기 피스톤(109)이 후진된 상태가 되고, 또한 상기 러버 재질을 갖는 퀵 밸브(107)가 고압에 의해 홀이 발생된다.However, such a conventional big blaster device leaks air through the complicatedly constructed air line 106 from the solenoid valve 112 during the continuous operation, so that the pressure balance between the primary balance chamber 108 and the tank 111 is maintained. The piston 109 is reversed due to inconsistency, and the quick valve 107 having the rubber material is caused to generate a hole by high pressure.

상기 실린더(109)가 후진된 상태에서 그 수리를 방치할 경우, 피스톤(109)이 고착되어 버리며, 후진된 상태에서 상기 토출구(113)에 광석이나 이물, 분진등이계속적으로 혼입되어 탱크(111) 내부에 물과 이물, 분진등이 누적되는 한편, 상기 피스톤(109)의 중요부분인 실린더 벽의 손상을 초래하는 문제점이 있었다.When the cylinder 109 is left in the reverse state, the piston 109 is stuck, and in the retracted state, ore, foreign matter, dust, and the like are continuously mixed in the discharge port 113 to the tank 111. Water and foreign matter, dust, etc. accumulate inside) and cause damage to the cylinder wall, which is an important part of the piston 109.

본 발명은 상기한 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 솔레노이드 밸브를 통하지 않고 에어탱크 내부에 직접적으로 에어를 공급하여 관련설비에 의한 에어의 누풍을 줄이고, 저장조 내부의 부착광을 제거할 수 있도록 한 저장조 내부의 부착광 제거용 빅 블라스터 장치를 제공하는 데 그 목적이 있다.The present invention has been made to solve the above problems of the prior art, by supplying air directly to the inside of the air tank without going through the solenoid valve to reduce the leakage of air by the associated equipment, to remove the attachment light inside the reservoir It is an object of the present invention to provide a big blaster device for removing the attached light inside the reservoir.
